Abstract: A polymer concrete comprising by weight about 40-70% coarse aggregate, about 20-55% of a fine aggregate such as sand, about 2-15% silica flour and about 8% to 12% furfuryl alcohol polymerized in situ with an acid catalyst produces a highly cross-linked concrete which contains no cement and is mixed with water. The furfuryl polymer concrete provides the broadest range of chemical resistance of all existing polymer concretes. The coarse and fine aggregate have a pH less than 7.0 and are provided with a specific size gradation.

Title: Deflection member and method of manufacture thereof
Inventor: TROKHAN PAUL DENNIS
IPC: D21F1/10

Granted: 1988-02-25
Abstract: @ Foraminous members (19) useful in making paper webs. The faraminous member of this invention has a macroscopically monplanar, patterned, continuous network surface (23) which serves to define within the member a plurality of discrete, isolated, deflection conduits (22). A foraminous woven element (43), such as a screen, is thoroughly coated with liquid photosensitive resin to a controlled depth above the upper surface of the woven element. A mask or a negative having opaque and transparent regions which define the pattern is brought into contact with the surface of the liquid photosensitive resin and the resin is exposed to light of an activating wavelength through the mask. The resin exposed to the activating light is hardened (cured). Uncured resin is removed from the composite leaving behind the woven element with the solid network formed by the cured resin.

Title: Complex quotient nuclear magnetic resonance imaging
Inventor: YEUNG HONG-NING
IPC: G01R33/20
Filed: 1984-11-08
Granted: 1988-05-11
Abstract: In an NMR imaging system, an image plane is scanned and NMR signals are collected over a plurality of image lines. The experiment is repeated, with the timing of the excitation pulses changed. Images are formed by performing Fourier transformations of the signal values. A ratio image is then formed by performing a complex division of the two images on a pixel by pixel basis. The ratio values cancel phase error effects in the image data and the use of complex numbers maintains the proper pixel polarity.

Title: Semiconductor power switch with a thyristor
Inventor: LEHMANN ERHARD DIPL ING
IPC: H01L27/07
Filed: 1985-06-26
Granted: 1988-03-17
Abstract: A power switch device comprises an asymmetrically blocking thyristor (ASCR), with which a diode is connected in series. The ASCR as well as the diode require only about one half the central zone thickness as compared with a symmetrically blocking thyristor laid out for the same blocking voltage in reverse direction (URRM). For the series connection of the ASCR and diode, this results in a much lower blocking delay charge (Qrr).

Inventor: LIEBEL WERNER
IPC: G09G1/16
Filed: 1985-04-29
Granted: 1988-10-20
Abstract: The generator has a video memory (5), a horizontal address control circuit (6) and a circuit (7) generating a vertical signal describing the vertical position of the video signal being generated. A comparator (11,14) generates a reference signal representing a point within the video signal line.

The comparator reference signal has a maximum when the vertical signal coincides with the output from the converter. The ref. decreases with increasing difference between the vertical signal and the output. When the difference exceeds a limit the ref. indicates the absence of the point in the measurement in the video signal line.

Abstract: Disclosed is a cutting device which is horizontally displaceable by means of double-acting guide cylinders and is vertically movable along vertical guide rods by means of a positioning device 10. Before cutting, the cutting device is brought into the preselected position by the positioning device. The heated cutting wire of the cutting device is connected to a current source via sliding contacts resting against ball bearings, over which the cutting wire is guided. The circuit of the current source contains a microswitch, the switch lug of which comes to rest against a plate during the forward movement of the cutting device and switches over the microswitch, thus terminating the heating of the cutting wire. This takes place at the moment when a cutting wire, after cutting through a material guided vertically over a cutting bar, penetrates into a notch in the cutting bar.
